4. RW reading tests
RW reading tests
- CD-RW tests:
For the RW tests we used the Ricoh 1-4x CD-RW media. We duplicated the Plextools 1.08 CD, using Nero 184.108.40.206 which was written on the Iomega Predator at 4x speed. The whole process took us 19:45" to complete, which was more or less what we've been expected. We have included the Lead-in and Lead-out time into this measurement.
We didn't use the writing process that CD Speed 99/Nero CD Speed offers, because the drive failed to co-operate with the program, due to it's specific harware (read the relative comment on the previous page for more information on this subject).
- CD Speed CD-RW Tests:
The drive reads with 6,39x speed a CD-RW media as the CD-Speed reports. The seek times are much higher than with normal CDR media (except for the Full Seek test) while the CPU usage for all speeds is very high (8x reading: 100%):
We used CloneCD (v220.127.116.11) and 5 original CDs - Euro 2000 (SafeDisc 1), No One Lives For Ever (SafeDisc 2), Rally Masters (LaserLock 1), Desperados (LaserLock 2) and V-Rally 2 Expert (SecuROM 2) - in order to test the reading time of Iomega Predator USB. We also tested the reading performance with backups of the original CDs, since the reading speed varies between original and backup media. The following picture shows the drive's reading/writing capabilities:
As you understand the drive's limited reading capabilities (6x) will not give you a great reading performance. The drive needed around 1hour to make images from our SafeDisc 1/2 protected CDs. The bad news are that it doesn't support the reading of the 96bytes SubChannel data which makes the backup of CD-Text, CD+G and LibCrypt PSX protected CDs impossible. You will not have any problems with SecuROM 2 CDs.
